Hab. Surinam, Spliffjerhn: — The above brief character is not calculated 

 to throw light on the species here intended, nor can much more be learned 

 from the full description. The author compares it with Als. nigra, Mart. 

 («. 25 of this work). 



33. A. pilosa, Martius et Galeotti ; " fronds ample pilose 

 ovato-lanceolate sub-bipinnale, pinna? patent lanceolate elon- 

 gate much acuminate deejily pinnatifid, upper ones gradually 

 smaller, segments linear oblong obtuse toothed at the apex, 

 the margins revolute glabrous above, veins parallel, the rachis 

 and costa hairy beneath, sori globose crowded submarginal 

 pilose, stipes and common rachis hairy." Martius et Gale- 

 otti, Syn. Fit. Mex. p. 78, /. 22. 



Hab. Mexico; Totutla, Colony of Mirador, at an elevation of 4000 feet 

 above the level of the sea, GaleoUi, n. <5405. — " Frond 4 — (5 feet. Pinnae 

 2—10 inches ; the lower ones a foot long, segments half an inch to an inch 

 long." — It is impossible from such a description and from such a figure to 

 offer an opinion on the affinities of this species. The veins are represented 

 as quite simple, parallel and nearly horizontal, and the sori, although 

 stated to be globose, are oblong in the plate.
